Companies in western democracies usually pay tax in addition to their workers and owners, but don't have representation in parliaments separate to that of their workers and owners. Questions about whether robots have the right to vote has more to do with their humanity and less to do with their tax liability in such societies.

At least for the time being, AI "workers" belong to someone. That person is represented and pays taxes.

That's peculiar, every single robot seems to have voted for the new Musk Kill All Humans Party. Oh well, that's democracy in action.
